To enable support for OptimizeMember, go to Affiliates → Settings → Integrations and check the box next to OptimizeMember:

Once enabled, AffiliateWP will automatically generate referral records when a customer successfully registers for your site after clicking on a referral link.

In Affiliates → Referrals the Reference column refers to the transaction ID from your merchant processor (Stripe, PayPal, Authorize.net, etc.) for the payment recorded in OptimizeMember.

Important notes:

  • Referrals will only be credited on the initial signup payment, and will not be created when subscription payments are recorded.
  • In order for referral tracking to work properly, your IPN / webhooks must be configured for OptimizeMember. Consult the OptimizeMember documentation for further information if you experience issues with referrals not being created properly.
  • Custom URL order links for PayPal are not supported. Only products and levels setup via the [optimizeMember-PayPal-Button] and [optimizeMember-Pro-PayPal-Form] shortcodes are supported.
  • The [optimizeMember-PayPal-Button] shortcode will not work on a multisite network.
